Romberg array Calculator

Calculates the Romberg array produced by applying Richardson’s extrapolation procedure, which forms the basis of the Romberg Method.

The final diagonal element so produced is the best estimate of the integral.

Trapezoidal Midpoint
Non-linear substitution (Midpoint)
 

The Romberg integration Rnn can be rapidly converged with the increase in n.
It is calculated by increasing the number of partitions to double from 2 to N=2n.
In the case of non-analytic at endpoints of f(x), you can calculate by Midpoint rule.
In the case of a periodic function, you can calculate by Non-linear substitution in x.
